摘要： A polarization plate is provided for use between a light source and a display panel, where the light source is configured to emit light having a plurality of planes of polarization and the display panel is configured to have a predetermined polarization axis. The plate includes a repolarization region and a prepolarization region. The repolarization region is configured to diffuse and to depolarize or rotate at least one plane of polarization of the light passing therethrough. The prepolarization region is disposed adjacent to and in contact with the repolarization region. The prepolarization region is configured to be substantially nonabsorbent, to allow passage of light having a plane of polarization that is substantially aligned with the predetermined polarization axis, and to prevent passage of light having a plane of polarization that is not substantially aligned with the predetermined polarization axis. In another embodiment, an interface is provided between the regions.

摘要： An electronic dimming system for use in projection displays is provided. In a first embodiment, the dimming system comprises a first non-absorbing polarizer, a variable polarization rotator, a second non-absorbing polarizer and a heat absorber. The first non-absorbing polarizer receives light from a light source and passes the light of a selected polarization to the variable polarization rotator. The variable polarization rotator selectively rotates the polarization of the received light. The light passes from the variable polarization rotator to the second non-absorbing polarizer. The second non-absorbing polarizer passes only light of a second selected polarization. The light that passes the second non-absorbing polarizer is passed to the display, where it is used to illuminate the display. The system provides the ability to control the amount of light passed to the display by selectively rotating the polarization of the light with the variable polarization rotator.

摘要： A position light (200) for use on an aircraft. The aircraft position light uses light sources (302) installed into an alignment fixture (304) which optionally carries away heat generated by the light sources. Light emitted by the light sources is directed into a first prism (308), which distributes and directs the light. A second prism (324) is used to further shape the pattern of the light. A lens (206) is installed over the position light (200) to protect it from the elements.

摘要： A screen assembly that combines an angle re-distributing prescreen with a conventional diffusion screen is disclosed. The prescreen minimizes or eliminates the sensitivity of the screen assembly to projector location. The diffusion screen provides other desirable screen characteristics. The prescreen is preferably formed by a collection of light transmitting and refracting elements, preferably spheres 80, partially embedded in a light blocking layer. Toward the back of the spheres 80 are effective apertures 82 where the light blocking layer 81 is absent or at least thinner than in other regions toward the side of the spheres. The projected image enters spheres 80 through the effective apertures 82, and exits the spheres 80 centered orientationally about the normal to the lens axis. The re-oriented light rays then enter the diffusion screen for viewing.

摘要： A system and method for optimizing image uniformity in a head-up display (HUD) are provided. An imaging subsystem is characterized in that if light of a first uniformity is propagated therethrough, an uncompensated image would be displayed to a user via uncompensated image light. The uncompensated image light has first and second portions with respective first and second values of a radiant property. A difference between the first and second values is a first amount. The light source is configured to emit source light of a second, predetermined uniformity through the imaging system such that a compensated image is displayed to the user via compensated image light. The first portion of the compensated image light has a third value of the radiant property, and the second portion of the compensated image light has a fourth value of the radiant property. A difference between the third and fourth values is less than the first amount.
